   @davidzollo @DanielLeens I would like to work on this issue
   
   I checked the current file source path and BaseFileSource is still bounded. 
FileSourceSplitEnumerator discovers the configured files once and signals no 
more splits, so appended bytes are not discovered again
   
   For the first slice I propose supporting append-only LocalFile text input. 
The source would poll file size, emit only the newly appended byte range, and 
checkpoint the file identity and consumed offset so restore does not duplicate 
data
   
   I would keep file rotation, truncation and in-place modification outside the 
first slice unless you prefer those semantics to be included now
   
   Does this scope look reasonable? thanks!
